Combines the properties of a Blue bulb with a Actinic Blue 03 bulb producing a unique spectrum that encourages both bluing in SPS corals and fluorescence in capable corals. Also helps balance out a washed-out/yellow hued tank. Great as a supplement to metal halides or in combination with a 6500K Sun Pro or Aquablue Special bulb.

We have 24, 36, 48, and 60" instock.
